PolyMax Buyer's Guide

PolyMax® is a durable, corrosion-resistant, washable material that can be used for a variety of agricultural and commercial applications. Though it is somewhat flexible in nature, PolyMax is extremely strong.

What is the difference between PolyMax sheets and rolls?

PolyMax plastic sheets, also commonly called PolyMax wallboard, are more aesthetically pleasing than the rolls because they are constantly kept flat, unlike the rolls which develop a slight bend due to the way they are produced. Sheets only come in white, while rolls come in black and white.

What is the difference between white and black PolyMax?

The black material is denser and has a longer life than the white material, which is made from HDPE (high-density polyethylene). White is available in rolls and sheets, while black only comes in rolls. Black rolls have a higher UV resistance than the white, and are made of a high molecular weight polyethylene (HMWPE) for superior impact and abrasion resistance.

Where can PolyMax be installed?

Flat sheets and rolls: PolyMax can be installed on walls in stalls, milking parlors, shops, processing plants, kennels, barns, car washes, skating rinks and more. This material works well as a wall covering, because it is impact resistant and easy to keep clean.

Corrugated sheets: Corrugated PolyMax is ideal as a ceiling covering, especially in building,s such as poultry houses and milking parlors, because the corrugated material will not sag over time. When PolyMax is used to cover a ceiling it should be less than ¼" thick. The corrugated material can also be used as livestock divider panels. Generally, corrugated PolyMax is twice as strong as its thickness.

Black PolyMax: This black material is ideal as a bed liner in trucks. Bed liners made of black PolyMax can hold rocks, gravel and stone, among other materials. This material is so versatile, it can also be installed on the underside of boats with the same success.

White PolyMax: White PolyMax can be used as manger liners to keep livestock feed sanitary. We recommend using the white rolled PolyMax for this application, because the brightness is more appealing to the livestock than black rolled PolyMax would be. The rolls can be installed in feed bunks containing hay, corn and grain.

How do you install PolyMax?

Prior to installation, PolyMax should be stored at or above the normal operating temperature of the building for a minimum of 48 hours. This is recommended because the material tends to expand and contract with temperature changes, and keeping it at this temperature will allow the material to assume the temperature characteristics of the building. To flatten rolls out, they should be spread out in the sun for a period of time prior to installation.

Predrilled holes one size larger than the fastener should be made, so the material does not bind up around the fastener. Fastener holes should not be less than 1" away from any panel edge, as this will weaken the PolyMax material. If you need to cut the sheets or rolls prior to installation, any power or hand saw with a fine tooth blade or abrasive disc is an ideal tool for the job.

When installing multiple pieces of corrugated PolyMax as a wall covering, the ends and sides should overlap. The sides should overlap 1" along the flat edge of the panel, while the ends should overlap 2". Start from the floor and work your way to the ceiling.

Generally, PolyMax will only have to be installed once, and should not need to be replaced for a long period of time. The slick surface of this material makes it difficult to use glue or silicone, and we do not recommend this method of installation.

If you are installing PolyMax sheets, you may want to consider using some moldings to help seal the boards and create a finished look in your building or barn. We sell a variety of moldings in white PolyMax and stainless steel, including H-Moldings, Exterior Corner Moldings and Joints.

What fasteners can be used when installing PolyMax?

All fasteners used for PolyMax installation should be rust proof and have a neoprene gasket or washer. Elevator bolts or construction screws with ¼" washers are ideal fasteners if you are installing the product on wood or as a bed liner. A Tek Screw or pan head screw should be used if you plan to countersink the fastener into the PolyMax. In this case, the PolyMax should be thicker than ¼". When using PolyMax as a liner, a small concrete wedge anchor,rivet, or an UltraCon® fastener should be used. Regardless of what fastener you choose, it should not be over tightened to allow for the expansion and contraction of the material.

Is there maintenance involved with PolyMax?

PolyMax is extremely easy to clean and sanitize, making it ideal for locations that need to be kept clean, such as milking parlors and poultry houses. We recommend simply hosing it down regularly and using a scrub brush if necessary.
